I was surprised to see a new version of the old IceS client — after all, it wasn’t supposedly developed anymore. The reason I’ve packaged it is that it supports streaming of MP3 data. My Audiotron doesn’t handle Ogg Vorbis, which is the only format supported by the new IceS client.
So, to stay current on the version, I’ve upgraded the ices-mp3 package to version 0.4. It adds FLAC support, actually, so that might be a reason to upgrade. Note that it transcodes the data, though, so you’ll need the CPU power to decode FLAC and encode it to MP3 (using LAME).
